Unfortunately I forgot to port one aspect of the mips-linux implementation:
common ppc code needs to pass tdesc_data to the osabi handler in the first
place.  Due to this oversight, the new ppc_linux_init_abi code didn't
actually do anything.  I'm somewhat surprised that it still appeared to
work ...

Anyway, this patch adds the missing piece: rs6000_gdbarch_init now passed
in the target description (and architecture-specific part) via the
info.tdep_info hook, similar to mips.

Tested on powerpc-linux and powerpc64-linux, both native and using local
gdbserver mode.  No change to the test results.

Committed to mainline.

Bye,
Ulrich


ChangeLog:

	* rs6000-tdep.c (rs6000_gdbarch_init): Set up info.target_desc
	and info.tdep_info before calling gdbarch_init_osabi.
